Titanic weather

February 8, 2008

Water melts from a liquid to a solid at 0°C, and it boils from a liquid to a gas at 100°C. The average temperature on Earth is 14°C which means that water is usually a liquid on Earth. Liquid water is REALLY important for life on Earth.

Methane melts from a liquid to a solid at -183°C (yes, minus), and it boils from a liquid to a gas at -162°C. Titan, which is the largest moon of Saturn, has an average temperature of -179°C which means that Titan is really cold and that methane is usually a liquid on Titan.

So just like Earth has a water cycle, Titan has a methane cycle with methane clouds and everything – cool.

People only use 10% of their Brains … NOT!

‘Humans only use ten percent of their brains’ is a myth!

It turns out that we use virtually every part of the brain, and that most of the brain is active almost all the time. If you are still not convinced think about this: the brain represents three percent of the body’s weight, and yet it uses 20 percent of the body’s energy.

Although research is still pending on Homer Simpson’s brain:
